ad positioning question

I am trying to create multiple ads (2-across, 3-across, etc) that will float left to each other using Listmania. The ads are 187 px across going into a 585 px container with padding. The problem is that they are not aligning left to one another, but are aligning vertical (stacking). I’ve tried changing various styles with no luck.

Any advice on making the ads behave?

I resolved my question and will be posting a detailed explanation shortly.

Please, let us know how you did it? Can you show us how it looks like in your site?
